As of a few days ago, some Safari webpages (the first and most frequently-occurring of which was Facebook's News Feed) would start loading but then freeze up. I went into Activity Monitor, and while it did say that Safari Web Content wasn't responding, it also said that Flash Player (Safari web plugin) wasn't responding. Force Quitting the Safari Web Content didn't do anything; the page just reloaded and froze up again, but when I forced Flash Player to quit, the misbehaving webpage refreshed and worked perfectly. After several more instances of the problem I uninstalled and reinstalled Flash Player, and the problem happened again.
I've currently got Flash Player uninstalled for stability's sake, but I can't live a Flashless life forever. How can I fix the problem?
UPDATE: It just happened again after I attempted a reinstall. This time, I checked my Flash version.
OS X 10.10.2, Safari 8.0.3, Flash "NPAPI Plug-in version 126.96.36.1995 is installed."
